6 Claims.

This invention relates to packages more particularly for articles havingseparable parts such as expansion bolts, and aims to provide an improvedpackage which may be conveniently and economically assembled and whichhas relatively great strength and rigidity, while at the same timepermitting the separable parts to be arranged in a manner facilitatingready use of the articles.

Among other objects, the invention permits of separating the nuts forthe bolts from the shanks of expansion bolts and segregating these partsduring shipment, thus effecting a saving in labor which would otherwisebe required first, by the manufacturer, to place the nuts on the shank,and later, by the customer, to remove the nuts from the shanks beforethe bolts could be used. As a further object, the invention provides forassembling the bolt shanks and the separable expansion members in unitswithout the nuts, and maintaining the shanks and separable expansionmembers in. normal assembly during shipment and until the bolts are usedand the nuts applied, thus effecting great convenience and a furthersaving in labor.

The invention contemplates further an orderly assembly of the articleunits and the maintaining of said units and their separable parts insubstantially fixed relationship during shipment, so as to minimizemovement of the articles within the package. By means of the substantialrigidity thus attained, the articles may be shipped in a relativelylight carton, without objectionable rattling or danger of breaking thecarton, since the mass of the articles maintains its original volumewithout shaking down as usually occurs with articles packed in a mass atrandom. Such shaking down is highly objectionable since it rendersdifficult the choosing of the correct size of carton for a given num berof articles, and when the articles have been shaken down and thus occupyless space, the carton tends to become broken both bythe thrusts of thearticles upon the interior of the carton and the pressure of otherpackages upon the now partially empty carton. My'invention obviates thisand permits a number of packages to be juxtaposed and the strainsdistributed equally throughout the entire mass.

The invention will be explained more fully by reference to theillustrative embodiment thereof shown in the accompanying drawing, inwhich the invention is applied to expansion bolts.

In the drawing, Fig. 1 is a plan view of a pack age embodying myinvention, the cover of the package being omitted and the other partsbeing broken away for convenience of description; Fig. 2 is a sectiontaken on the line 22 of Fig. 1, but with the cover in place; Fig. 3 is asection taken on the line 3-3 of Fig. 2; Fig. 4 is 1930. Serial No.491,342

a perspective view of the parts shown in Fig. 1, broken away forconvenience; and Fig. 5 is an exploded view of the separable parts of anexpansion bolt.

Since my invention finds particular utility in the packaging ofexpansion bolts, I have illustrated one such bolt which frequentlyconsists of a shank l and separable expansion members such as theconical member 2, the cylindrical member 3, and the washer 4. When theconical member 2 and the cylindrical member 3 are slid upon the shank 1,as shown in Fig. 3, the members 2 and 3 being bored concentrically withthe shank, the conical member 2 contacts with the cone-like head In ofthe shank and the cylindrical member 3 contacts with the conical member2. If the washer 4, which is of relatively hard metal, be then placedupon the shank to contact with the cylindrical member 3 and a blow bedealt to the washer upon its entire face, the cone-like head 1a willspread laterally the conical member 2, which is of softer metal than thehead, and the conical member 2 will spread laterally the cylindricalmember 3 which is of still softer metal than the conical member 2. Thewasher is desirably of larger diameter than the softer parts to preventthe softer metal from flowing up around the washer when the latter isstruck. Thus if the bolt be located in a recess drilled in concrete, forexample, the lateral expansion of the members 2 and 3 will lock the boltto the concrete and pre vent its withdrawal from the recess. An objectmay then be secured to the bolt by means of the nut 5.

Obviously, until the bolts have been put into use as just described,when the nut 5 is off the bolt, the parts 2, 3 and 4 are in slidableseparable relation with respect to the shank 1. In order to save laborof the user, the parts 1, 2, 3 and 4 should desirably be assembled atthe factory and shipped in assembled condition.

If the nut 5 also be applied to the shank of the bolt however, to retainthe other parts in assembled condition, the nut would have to be removedbefore the bolt could be used, and the labor thus involved would offsetany saving in labor to the user by having the parts shipped to him inassembled condition. My invention permits of shipping the parts inassembled condition without the necessity of applying the nuts to holdthe other parts together.

I have shown a box such as the carton 6 adapted to receive a quantity ofbolts in parallel rows with the heads of the bolts resting on the bottomof the carton. The carton has the usual cover '7 which may convenientlytelescope upon the carton 6. The upper ends of the bolts desirablyterminate short of the upper ends of the carton 6 to provide a spacebetween the bolts and the cover 7 for a container such as the envelope 8in.

which may be placed the nuts 5 for the bolts. The envelope may then besealed if desired.

It will be observed that the separable parts of the bolts as here shown,with the exception of the nuts, are in normal assembly in the carton 6.These parts are maintained in said normal assembly during shipment bymeans next described.

To conveniently define parallel rows of the bolts, I place thin divisionstrips 9 made of cardboard or other suitable inexpensive material in thecarton 6, said division strips being disposed between and contactingwith the slidable members here shown as the conical member 2 and thecylindrical member 3, but not extending above the outer ends of saidmembers. For instance, the division strips 9 may conveniently terminatebelow the washer 4, as shown in Figs. 2, 3 and 4.

To keep the separable parts of the bolt on the shank 1, I provide afiller between the separable members and the end of the bolt which isopposite the head la, and means maintaining said filler in position toprevent the separable parts from sliding off or otherwise becomingremoved from the shank. In the illustrative construction, the fillerstrips 10 contact with the washers 4. These filler strips extend acrossthe carton 6 and are desirably transverse to the division strips 9, thuscontributing strength to the package. There is a filler strip betweeneach two adjacent rows of bolts and the filler strip is of sufficientthickness to prevent the separable parts of both rows of bolts frompassing the filler strip. To maintain the filler strips in position, Ihave shown a keeper sheet 11 transverse to the bolts and to the fillerstrips. As illustrated in this instance, the filler strips 10 extendabove the threaded ends of the bolts and the keeper sheet 11 contactswith the filler strips. The keeper sheet is maintained in position bymeans contacting with the cover of the box. As shown, the envelope 8,already referred to as a container for the nuts 5, is disposed upon thekeeper sheet 11. Thus, when the cover 7 is upon the carton 6, as shownin Figs. 2 and 3, and secured in position by any suitable means (nothere shown) the parts are maintained in assembly. The package has greatstrength and rigidity, rattling of the parts is minimized, and arelatively light carton suffices for carrying a relatively heavy weightwithout danger of breakage of the carton.

When the cover is removed by the user, the parts of the bolts with theexception of the nuts, are in normal assembly for ready use and the nutsare conveniently segregated.

Such changes be made as fall within the scope of the following claimswithout departing from the invention.

Having thus described my invention I claim:
